As I understand, to use Joomla! plugin events from my user code, I first need to load the plugin class (which registers the named functions as events in the event dispatcher):
Then I can trigger events from my user code:
$dispatcher = JDispatcher::getInstance(); trigger('onInit');
How does the plugin system handle name collisions between events? For example, the
captcha plugins have an
onDisplay function/event, as do the
editor plugins. What happens when I call the following after the previous code?
I believe this will trigger the
onDisplay event on both the group of
captcha plugins, and the group of
editor plugins. It seems like the
trigger method of
JEventDispatcher would need a parameter for at least the group of plugins to act on. Do I get all plugins with an
onDisplay function firing, and I have to sort out what is garbage? What if a non-relevant plugin running with garbage input has an exception on that input?
